Case ReportsCOVID-19 infection produces subarachnoid hemorrhage; acting now to understand its cause: A short communication.
In the medical literature, some case reports on the association of the COVID-19 infection and occurrence of spontaneous subarachnoid hemorrhage (SAH)have been reported Aim of the present paper is to search the causes of this association The diagnosis of COVID-19 was based on the real-time reverse-transcription polymerase chain reaction (PCR) test and computed tomography (CT) of the chest. There were four patients, whose median ages were 46,758, ranged 36-54 years). In conclusion, Spontaneous SAH can occur in the early and late course of COVID-19 infection. Its early recognition of the patient with spontaneous SAH is imperative.

A case series and review of the mononostril endoscopic transnasal transsphenoidal approach: Safe and effective in a low resource setting.
A transnasal transsphenoidal (TNTS) approach can be performed through a binostril or mononostril technique. The binostril technique is generally preferred, however the mononostril may be an underutilized approach with significant benefits. ⋯ Based on a literature review, binostril TNTS surgeries have longer operative time and a higher risk of epistaxis. According to our experience, post-operative patient comfort and satisfaction are higher with the monostril approach. Furthermore, this technique is easier to teach, ENT assistance unnecessary, and thus especially advantageous in low resource settings. Our CSF leak and tumor recurrence rates were lower than reported binostril rates in the literature. The mononostril technique is both safe and effective and should be strongly considered for an appropriately pre-selected subset of pituitary adenomas.

Meta AnalysisThe analgesic effect of intravenous lidocaine versus intrawound or epidural bupivacaine for postoperative opioid reduction in spine surgery: A systematic review and meta-analysis.
Pain management following spine surgery remains a challenge. The significant use of opioids may lead to opioid-related adverse events. These complications can increase perioperative morbidity and rapidly expend health care resources by developing chronic pain. Although intraoperative pain control for surgery has been studied in the literature, a thorough assessment of the effect in spine surgery is rarely reported. The objective of the present study was to examine the outcomes of intraoperative intravenous lidocaine and intrawound or epidural bupivacaine use in spine surgery. ⋯ The results of the present meta-analysis indicate that lidocaine and bupivacaine use may decrease postoperative pain and opioid consumption. Lidocaine had a stronger effect on the reduction of opioid consumption compared to bupivacaine.

Computed tomographic angiography to analyze dangerous vertebral artery anomalies at the craniovertebral junction in patients with basilar invagination.
Failure to detect dangerous anatomic vertebral artery anomalies (AVAAs) and dangerous functional vertebral artery anomalies (FVAAs) at the craniovertebral junction (CVJ) in patients with basilar invagination (BI) can result in major complications such as intraoperative vertebral artery injury, brain infarctions, and even death. Iatrogenic vertebral artery injury is a rare but severe complication of cervical spine surgery. We aimed to evaluate dangerous vertebral artery anomalies at the CVJ in patients with BI using computed tomographic angiography (CTA). ⋯ Dangerous vertebral artery anomalies at the CVJ have a high incidence in patients with BI. Preoperative CTA is highly recommended in such patients to identify anomalous vertebral arteries and reduce the risk of intraoperative injury.

Supratentorial intracerebral hemorrhage volume and other CT variables predict the neurological pupil index.
There is growing interest in the ability of automated infrared pupillometry to assess severity of neurological illness. We studied the correlation between computed tomography (CT) indicators of intracerebral hemorrhage (ICH) severity with objective measures of the pupillary light reflex (PLR), and hypothesized that hemorrhage volume would predict the Neurological Pupil index™ (NPi™), an indicator of pupillary reactivity. ⋯ ICH volume and shift of midline structures correlate with NPi, and abnormalities in NPi can be predicted by hematoma volume and other CT indicators of ICH severity. Future studies should explore the role of NPi in detecting early hematoma expansion and worsening midline shift.
